Avian pox viruses (APVs) have been reported to cause infection in diverse avian species worldwide. Herein we report the first case of APV infection in a free-living bird, a subadult crested serpent eagle (Spilornis cheela), in Taiwan. In addition to the typical wart-like lesions distributed on the cere, eyelid, and face, there were also yellowish nodules below the tongue and on the hard palate. Phylogenetic analysis of the 4b core protein gene showed that the APV is very close to that found in white-tailed sea eagle (Haliaeetus albicilla) in Japan recently. Because both cases are located on the same major flyway for migratory birds, the impact of this virus with regard to the wild and migratory raptor species along the East Asian-Australasian Flyway and West Pacific Flyway requires immediate investigation.
据报道，禽痘病毒（APV）可在全球多种禽类中引发感染。在此，我们报告台湾地区首例自由生活鸟类感染禽痘病毒的病例，该鸟类为亚成体凤头鹰（Spilornis cheela）。除了在蜡膜、眼睑和面部出现典型的疣状病变外，舌头下方和硬腭上也有淡黄色结节。对4b核心蛋白基因的系统发育分析表明，该禽痘病毒与最近在日本白尾海雕（Haliaeetus albicilla）中发现的病毒非常接近。由于这两起病例都位于候鸟的同一条主要迁徙路线上，因此这种病毒对东亚-澳大拉西亚迁徙路线和西太平洋迁徙路线沿线的野生和迁徙猛禽物种的影响需要立即展开调查。
